Arouse, Jun 20, Buy it now – Add to Watch list Added to your Watch list. The pins are labeled different on the spec sheets but they are electrically the same.

I am curious about the function of Q in the power supply. Take a look apo605 our Returning an item help page for more details. Also this might come in handy if anyone in the future comes across this post. The time now is I wouldn’t do what you have done in the diagram above.

Get the item you ordered or your money back. Will the Surface mount one work? Information and picture clarity compositions should look like this post. I don’t see the problem in tying them to ground instead of the sources of the FET why do you thing this will be an issue? This item doesn’t post to United States.

Space is limited on the board and as I will use toner transfer method for the PCB the traces cannot be too thin. Learn more alp605 opens in a new window or tab. I would like to know because i have about 50 of these viewsonic monitors that have this power board in them.

The IRF should work since it has the same Rdson. Can I omit the two 2N transistors and drive the gates directly from the microcontroller maybe using a series resistor? I have already completed the PCB layout and connected the emitter of the 2N directly to ground. I could buy a SMD to Throughhole adapter and use that.

The reason i posted this in this section is because this is a very common “problem” chip on the DACM power board that is used in Multiple monitor brands. There will be no PWM. AOP Replacement Can you explain about the heat issue? Add to Watch list.

Seller information ipertronica-it Bay area My Country: The higher the Rdson the more heat it will generate. Originally Posted by Alup.

The reason it is running hot is due to poor DC filtering of the power supply, if the DC filter caps are not filtering properly due to high ESR and lower capacitance, the high frequency AC ripple will be riding through to the inverter circuits and modulate the high frequency switching of the inverter circuits the frequency of the SMPS and the inverter PWM are not the same, both signals will add and subtract to produce the side band frequencies, so the switching frequency will be off from the original design requirement which will cause the transformers and the switching devices to get hot.
